DEVICE FOR COILING METAL RODS.

SPECIFICATION forming part of Letters Patent No. 428,971, dated May 27,1890. Y Application filed December 7, 1889. 'Serial No. 332,927 (Nomodel.) Y

T0 @ZZ whom t may concern:

Be it known that I, FRANK G. TALLMAN, a citizen of the United States,residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented new and useful Improvements in Devices forOoiling Metal Rods; and I do hereby declare the following to be a full,clear, and exact description of said invention, reference being hadto'the accompanying drawings, and to the letters of of reference markedthereon, which form a part of this specification.

My invention relates to improvements in devices for coilin g metallicrods as they emerge from the rolls.

The object of my present invention is to provide a device by whichmetallic rods are thrown into coils as they emerge from the rolls, saidcoils being arrested by a suitable standard.

In the drawings, Figure 1 is a View in perspective of a set of rolls,guide-tubes, coiling devices, and the standard for catching the coils.Fig. 2 is a sectional view of my improved coiling device. Fig. 3 is aview in perspective of the coiler. Fig. 4 is an edge view. Fig. 5 is afront view. Fig. 6 is a rear view. Fig. '7 1s a sectional view of theguidetube. Fig. is a view in perspective of a modiiication of thecoiler. Fig. 9 is a longitudinal sectional View of the device shown inFig. 8. Fig. lO is an end view of the same.

A indicates the housings, and B the rolls mounted therein, which are ofthe ordinary construction of rolls for rolling metallic rods.

C is a guide-pipe mounted in suitable supports in front of thefinishing-grooves D in the rolls B.

E is a supplemental guide-pipe adj ustably mounted in the standard orsupport F by means of an inverted-U -shaped bolt and nuts, so that itcan be adjusted longitudinally to direct the rods into the coilingdevice at any suitable angle.

G is the coiling device mounted in a sleeve or bearing H in the upperportion of the support F, said coiling device consisting of a sleeve I,having a grooved pulley-wheel K at its outer end adapted to receive adrivingbelt L, by which the coiling device is driven from any suitablesource of power.

The central portion of the pulley-wheel K is provided with a series ofopenings M, which are separated by the spokes or division-platesterminating in the pyramidal guide O, which projects toward the rolls,and the guide-tubes O and E. i

The pyramidal guide O may be made concave, as shown in Fig. 3, so thatthere will be no possible chance of theA end of the rod catching anddoubling up in the coiler; but the rod will be invariably directedthrough one or the other of the openings M. The rod in its coilingmotion is held against the spokes or division-plates M by the concavesurfaces of the pyramidal-shaped guide O; but as soon as the forwardmotion of the rod ceases by reason of its exit from the rolls B the endof the rod is free to move within the coiler without subjecting the sameto a twisting action. The openings M on the outer face of the coiler areprovided with bosses P, so as to increase the surface and thus prolongthe life of the coiler.

R indicates a standard or catcher for receiving the coils as they areformed by the coiler G. Each standard may be mounted in pairs on arevoluble shaft S, and of the construction described and claimed in mypatent, No. 412,565, dated October 8, 1889, and a further description ofthem being deemed unnecessary in this connection.

I do not wish to be understood as limiting myself to the number of holesM or spokes N used in the coiler, nor to the form or section of theholes or spokes shown, for the reason that a common pulley with apyramid or other like device for holding the rod out toward the end ofthe spokes or the sides of the holes will work equally as well.

The supplemental guide-tube E enables the operator to direct the rodsand also to adjust the shape of the coil by moving the said pipe to orfrom the coiling-wheel, so that the angle formed by the rod in goingthrough the coiler will be greater if the outer end of the pipe E isnearer the wheel than it would be if th'e end of the pipe was fartherremoved from the coiler.

In Figs. 8, 9, and 10 I have shown a modification of the coiling-wheelshown in Figs. 1, 2, 3, 4, 5, and G, and, instead of -using the pyramidal central portion- O, I employ a U-shaped guide B', bolted to the wheelL on IOO the side next the nishing-rolls and of such Y a shape as toinsure the delivery of the front end of the rod into a particularopening M in the Wheel. vhen this opening opposite the guide B is Wornout, the tap-screwpB" is unscrewed and the guide B moved around toanother opening, and so on until the wheel is Worn out. It will bereadily seen that this construction absolutely prevents the front end ofthe rod from striking anywhere except at the proper point on the cone todirect it into and through the opening in the coilingavheel, and givesme the advantage of the Whole Wheel with the holes M, of such shape thatthe back end of the rod will not twist up.

That I claim, and desire to secure hy Letters Patent, is-

l. In a device for eoiling metal rods as they emerge from the rolls, arotating wheel or pulley having openings, and a guide or guides securedto or formed with said wheel placed in the path of the rod as it emergesfrom the rolls, the sides of said opening in the wheel adapted to engagethc rod and deflect it, thus imparting to the same by the rotation ofthe Wheel a ceiling or spiral motion, as set forth.

2. In a device for coilingmetal rods, a rotating wheel or pulley toimpart a ceiling or spiral movement to the rod as it passes therethroughfrom the rolls, the spokes of said pulley constructed of substantiallyoval or of triangular section with the edges of the oval or triangularspokes inclined toward the advancing rod, as set forth.

3. In a device for eoiling metal rods as they emerge 'from the rolls,the eoiler G, provided with a series of openings M, and apyramidalshaped central portion O, for directing the rod to one of theopenings.

4. In a device for ceiling metal rods as they emerge from the rolls, thecoiler G, provided with a series of openings M, and a pyramidalshapedportion 0, iu combination with the adjust-able supplemental guide-tubeE, as set forth.

5. In a device for ceiling metal rods as the)y emerge from the rolls,the adjustable supple mental guide tube E, placed between the guide-tubeC and the coiler G, as set forth.

In testimony whereof I affix my signature in the presence of twosubscribing witnesses.

FRANK G. TALLMAN.
